%%DNA%% polymerase: an enzyme that is usually involved in DNA replication. This enzyme uses deoxyribonucleotides (dNTPs) and a primed template as a substrate to synthesize a new strand of ssDNA that pairs with its template to form dsDNA. There are many different kinds of %%DNA polymerase%%, but in this book we collectively refer to them as "%%DNA polymerase%%" for simplicity.
